Application filed llctober 23, 1916. Serial N0. 127,192.

To all whom it may concern:

Be it known that l', WILLIAM l?. WAGNER, a citizen of the United States, residing at Ambrid e, in the county of Beaver and State o Pennsylvania, have invented certain new and useful Improvements in' Liquid-Dispensers; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has,for its principal object to improve upon the construction of gasolene and other liquid dispensing apparatuses to such an extent as to permit the purchaser to ascertain exactly the amount for which he A. further object is to provide improved means for lling and emptying the meas# i drawing uring tank.

With the foregoing general objects in view, the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully Ldescribed )and claimed, the descriptive matter being supplemented by the accompanying which constitutes a part oit' this specification and in which a vertical section of theimproved apparatus is shown. f

lin-the drawing the numeral 1 designates a vertically disposed glass cylinder whose ends are'closed by upper and lower end plates 2 and 3 respectively secured in place y vertical stay bolts 4, packing gaskets 5 being provdedfor obtaining Huid tight connections. A liquid supply pipe' 6 enters the upper end of the cylinder 1 and is provided `like ma with an inwardly opening check valve 7, and a compressed air supply pipe 8 enters the casin of said valve. 'lhe lower end of the cyln er is provided with a liquid discharge pipe9 from which a hose 9 or the lead if the apparatus is to be used for lllng the tanks of automobiles, 'sald provided with a suitable valve 10. A gra uated scale 11 is rovided in order that theeract number o -gallonsof liquid supplied to the tank through the pipe 6 may be in full view of the purchaser. v

A vertical glass tube 12 is disposed on the exterior of the tank 1 and by means of 'upper and lower pipe connections. 18 and 14 is in communication with the i'nterlor pf said vcylinder or tank, the upper connections 18 serving merely as a vent to permit air to be displaced :from the tube 12 as the liquid therein simultaneously with the raisingrof the level in th`etank or cylinder 1. he tube 12 serves as atguideway for a common type of variable volume hydrometer 15 so t at the purchaser may ascertain the exact grade of the gasolene yor other liquid dispensed from the apparatus.

In order that air may escape from the cylinder or tank 1, as the liquid level rises,

rises it is necessary to provide some suitable vent and for this purpose, a valve 16 is shown in the upper pipe connections`13. lt is also l,essential that means be provided for cutting 0H the air pressure throughthe pipe 8 when the tank is being filled. lF or this purpose, a valve 17 is provided for said pipe and in view of the fact that when valve 16 is open, 17 must be closed and vice versa, l prefer- I ably provide operating connections between the' two for simultaneously actuating them.

rllhe connections in question may be of any n suitable construction but forillustrative purposes both valves are shown provided with operating arms 18. connected by means of a link 19 which is shown provided with an opcrating handle 20.

In operation, let us assume that three gallons of gasolene are to be sold. The valve 10 being closed, the handle 20 is operated'to simultaneously close the valve 17 and ,open 16. Since the air within the tank cannow escape, the liquid flowing through the pipe 6 under pressure will be deposited in the tank and when the level vreaches 3 on the scale 11, the handle 20 will be operated to close 16 and open 17. 'lhe inrush of compressed air through the pipe 8 upon this op- Bill eration, automatically closes the check valve n7 and when the valve '10 is now opened the passage of said air into the cylinder will quickly expel the contents thereof. It is to be observed that as the liquid rises in the tank, it maintains the same level in the tube 12, continuallyoating' the hydrometer 15 so that the purchaser can readily see the exact gradeof gasolene or other liquid. From the foregoing, taken in connection with the accompanying drawing, it will be understood that althoughthb device is vextremelv simple and-comparatively inexpensive, it will e elicient and will fulil a long A"felt need. l wish it understood in conclusion, however, that although certain specific details have been shown and described for( d im -illustrative purposes, numerous changes may be made within the scope of the invention as claimed. In most cases the tank l Will be of a size to Cmeasure as high as ve gallons but it is obvious that the size and shape of said tank may be varied as occasion may demand.

I lclaim:v

A liquid dispensing apparatus comprising a measuring tank having a graduated scale, a liquid-supply pipe discharging into said tank and having a check Valve opening to- Ward the same, a vent valve from the upper end of said tank to permit the escape of air While said tank is filling, a fluid pressure ,line discharging into said liquid supply pipe between said check valve and said tank, a cut oi' valve 1n sald fluid pressure line adjacent said vent valve, a single operating handle connected operatively with said Vent '20 and cut olf valves for simu] .neously closing one and opening the other, and a valved outlet from the bottom of said tank.

In testimony whereof I have hereunto set my hand in the presence of two subscribing 25
